Retire snd_sbc ISA sound card driver
Along with the snd_sb8 and snd_sb16 drivers. They supported ISA Creative Sound Blaster and compatible sound cards. Note that isa/sb.h is not removed, as it is still used by some PCI sound card drivers. ISA sound card drivers are deprecated as discussed on the current[1] and stable[2] mailing lists. Deprecation notices were added in e39ec8933be4 and MFCd to stable branches. Driver removals are being committed individually so that specific drivers can be restored if necessary (either in FreeBSD or by downstream projects).

-.Sh DEPRECATION NOTICE
-This driver is scheduled for removal prior to the release of

-.Sh SYNOPSIS
-To compile this driver into the kernel, place the following lines in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "device sound"
-.Cd "device snd_sbc"
-.Cd "device snd_sb16"
-.Cd "device snd_sb8"
-.Ed
-.Pp
-Alternatively, to load the driver as a module at boot time, place the
-following lines in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-snd_sbc_load="YES"
-snd_sb16_load="YES"
-snd_sb8_load="YES"
-.Ed
-.Pp
-Non-PnP cards require the following lines in

-.Ed
-.Sh DESCRIPTION
-The
-.Nm
-bridge driver allows the generic audio driver
-.Xr sound 4
-to attach to Creative Sound Blaster ISA (mostly SB16 or SB8, known as
-SoundBlaster Pro) compatible audio cards.
-.Pp
-The value of flags specifies the secondary DMA channel.
-If the secondary
-DMA channel is C, set the flags to (C | 0x10).
-For a sound card without the
-secondary DMA channel, the flags should be set to zero.
-.Sh HARDWARE
-The
-.Nm
-driver supports the following sound cards:
